The user's adjustment knob on their table has broken because the internal threads have stripped. This is a common issue in furniture with plastic adjustment mechanisms, leading to frustration when trying to adjust or disassemble the pieces.

Product/Service Opportunity:

A line of Durable Replacement Adjustment Knobs for Furniture.

Specific Product Suggestion:

    • Description: A range of knobs designed to replace broken or stripped plastic adjustment knobs on furniture like tables, chairs, and stands. These knobs feature a female thread.
    • Material Options:
      • Machined Aluminum (lightweight, strong, premium feel)
      • Die-Cast Zinc (durable, cost-effective for complex shapes)
      • Glass-Reinforced Nylon or other robust polymers (stronger and more wear-resistant than standard plastics used in OEM parts).
    • Features:
      • Variety of Thread Sizes: Offer common metric (e.g., M6, M8, M10) and imperial (e.g., 1/4"-20, 5/16"-18, 3/8"-16) thread sizes to fit a wide range of furniture bolts.
      • Ergonomic Designs: Star knobs, T-handles, fluted round knobs, or other easy-to-grip shapes.
      • Enhanced Durability: Focus on robust internal threads that resist stripping.
      • Aesthetic Options: Different finishes (e.g., black, silver, textured) to match various furniture styles.
    • Packaging: Could be sold individually or in small multi-size "Furniture Knob Saver" packs.
  2. Complementary Product/Kit: "Furniture Knob Rescue Kit."

    • Description: A kit designed to help users identify the correct thread and replace their broken knob.
    • Contents:
      • A selection of 2-3 of the most common sized durable female-threaded knobs.
      • A simple thread identification gauge (e.g., a card with printed rulers and thread examples, or a small set of male-threaded bolts for testing).
      • Clear instructions on how to measure existing bolts, select the correct knob, and remove stubborn broken parts (perhaps suggesting common household tools like pliers).

Expected Benefits:

  • Direct Sales Revenue: Income from selling individual replacement knobs or kits. This addresses a direct and common pain point.
  • Customer Loyalty: Providing a high-quality, durable solution to a frustrating problem can build a strong customer base.
  • Market Positioning: Become the go-to source for "upgraded" or "heavy-duty" furniture hardware components, differentiating from cheap original parts.
  • Sustainability Angle: Promoting repair over replacement of entire furniture items.
  • Ease of Marketing: Can be marketed online through DIY forums, furniture repair communities, marketplaces like Amazon/eBay, and targeted ads for keywords like "broken table knob," "stripped furniture knob," "replacement adjustment knob."
  • Scalability: The product line can be expanded to include male-threaded knobs, different knob styles, and other common furniture hardware failure points.

There's a better way. Nut and counter nut. Won't damage the thread

The plastic part has stripped its thread. Use a pair of pliers on the very end threads and unscrew it to the left. If it comes out You could try putting a 2 part glue in it, then screw it

If you add two nuts to the end of the threaded bolt, you can unscrew it by using the wrench on the inner nut. The outer nut will provide the resistance, and you’ll be able to unscrew it. Then

pliers will do the job for a quick fix, after that I would suggest replacing it with a proper bolt, not quite as finished or hand ready but at least you will be able to tighten it with a span

It looks like the plastic handle is stripped. The best solution would be to try to turn the bolt with pliers. It might help to pull the weight of the table vertically so it’s not pressing dow

Vice grips or pliers to get it out, then take both pieces to a hardware store and buy a new threaded knob with the same dimensions.
